Abstract

BIM is a powerful digital management tool that improves efficiency and promotes collaboration between AEC professionals across the lifecycle of a building and as a result has seen increasing use over the last decade. Despite the many recognised benefits of using BIM for new buildings into the O&M phase, a lack of research exists regarding similar use for existing buildings.
This research has two main areas of focus, firstly to investigate the importance of built assets and how BIM can be incorporated into their future management and secondly to explore various methods of capturing the data required to build a BIM model of an existing building. An analysis of existing literature was conducted to examine the first aspect and following this, a case study was undertaken which involved acquiring measurements from Port-Eco House using four different methods: tape measure; handheld laser tool, existing CAD drawings; and 3D laser scanner. The data obtained from each of the four surveys was subsequently used to construct individual BIM models, and a detailed analysis was performed to compare the different techniques and final outputs generated.
This research discovers that the output from the 3D laser scanning method is significantly more accurate than the other methods, being the only one allowing a highly accurate as-built model of the building to be created from the data obtained. However, due to the cost involved it can, in some instances, be preferable to rely on existing 2D CAD drawings should a full set be available. The study concludes by proposing guidelines regarding the most suitable method of measurement accounting for a range of factors and identifying areas for future research based on the findings.
